How to Cross Roses

Many people cross roses to develop unique specimens of flowers and sometimes help them grow and bloom better in their region. Crossing roses is not very difficult, but requires some small skill. It is basically taking one part of a rose plant and attaching it surgically to another rose plant(grafting). The top portion of the stem is known as the donor. The bottom portion is called the host. The union is the place on the plant where the donor and the host are sealed together. You surgically graft the less hardy donor to a rose plant better suited for the zone you live in. The donor then receives its hardiness and nutrition from the host, borrowing from its strength.
Crossed roses tend to flower much sooner than their counterparts. Roses are among the easiest flowers to cross because they are all nearly compatible with other rose plants.

Instructions

    • 1

      You may want to choose a red rose bush for the host. That is the original color of roses and the strongest. Choose another bush to cut the donor from.

    • 2

      Watch for blooms to fade form the flowers and petals drop but before buds swell up for the next flowering. Make sure that the knife you use is sharp. A clean cut is essential for successful rose grafting.

    • 3

      Find a nodule(button) on the host, cut a "V" right on the button, and make it deep and about an inch long so you can place the donor implant in the cut stem. Be sure while making the cut on the host stem, you see the wooden inner core of the stem.

      Next go to the donor rose bush, and find a new green, single branch and make the cut so that there are at least three nodules above the cut.

    • 5

      Match the cut on the donor to the cut on the host. Insert the implant in the "V" cut on the host for the union.

    • 6

      Use the tree seal paint to seal the union and use the green floral tape to bind the wound together. All the sap from the main stock will flow toward the implant and hopefully will take.
